WINDSHIELD TUBING.

Application led February'21, 1921. Serial No. 446,721.

To aZZ whom t may concern.'

Be it known that I, HUGO NnUMANfa citizen ofv the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Windshield Tubing, of which the following isI a specication, reference being had therein to the accompanying drawings.v

The invention relates to tubing which is used. for the formation of channel frames and is particularly applicable 'to vwind shields. The invention has for its object the provision of tubing formed of a channel member and-a surrounding outer tube havingseamed edges, the seams being at the outer edges of the sides of the channel member and within the tubing. With this arrangement, the seamsstrongly reinforce the tubing and are concealed so that the exposed surface of the outer tube is uninterrupted. lVith this object inl view, the invention resides in the novel features of construction as more fully hereinafter set forth.

In the drawings: .l

Figure 1 `is a side elevation of a portion of tubing embodying my invention;

Figure 2 is a transverse cross section therethrough showing the glass in place;

Figures 3, 4 and 5 are views similar to Figure 2 showing modified constructions.

Fig. 6 is an enlarged cross-section of the frame showing the seam vbetween the two metal members. f

Heretofore channel tubing has .been formed from .-tlatrstrips ywhich respectively form the channel member and the outer tubing having their edges seamed togethereither at the base kof `the channel member or outside the outer tube. With the first of theserconstructions, theseamed edges do not appreciably reinforce the tubing, while with the latter construction lthe seams are exposed' to view, are not protected from the weather land furthermore form cracks in the enamel-coating upon kthe tubing. By

i means of my improved construction, v.the

seams are concealed and being located at the outer edges of the sides of the channel member, they strongly reinforce the tube.

In 'detail and asshown in'Figures land 2,

the channel tubing Acomprises Vthe channelv member and the surrounding outer tube 2 having their edges 3 and 4 seamed to"- i -gethein VVThe edges 3 are U-shaped `'and open toward the sides 5 of the outer tube and the bases 6 ofthe Us are substantially` 1n the planes of the respective sides 7 of .the U-shaped channel member. The edges., 6()

4 of the channel member are U-shapedand open outwardly to cooperate with the "U- shaped edges 3 land be rigidly secured thereto. For the purpose of more rigidly secur` ing these edges to each` other, the U-shaped edges 4 are clamped between the Urshaped edges 3 and the sides 5 of the outertube.

F rom1the above description it will be y readily seen that the seams between `the channel membery 1 and the outer tube 2 form` I reinforcements for-the tubing, andare located within the tubing so thatV the exposed surface of the'outer tube is 11n-interrupted; i yand furthermore, the seams open into the space within the tubingV sol that whenV the A 75. .i

glass 8y is inkplace Vwithin the channel member, the seamsare concealed fromview asV well as from theweather. Y Y i i In the modified constructions shown in Figures 3, 4 and 5, the cross sectional contourV of the o` uter'tubesl are varied, but in and a tube enclosing the channel V each casev there is the same arrangement of memberand-havinginwardly extending por- Y ,tions return-bent around the inwardly ex-l tending edges o f said channel member. j

k2A device of the ,class described ,com`

vprising a channel member adapted to` re-y v.

ceivean edge of a transparent member, said channel member ha-vlng U-shaped portions at its-outer edges, and a tubeenclosing said 1 channel member and having return-bent portions abutting opposite sides of the transparent member and kinterlocking with the U-shaped portions. of said channelmember;V

In testimony whereof I aiiix my signa-ture.V Y I' HUGO NEUMAN.V
